Purge more (last?) comments from install scripts by removing all

comments that, being on the end of code lines, cannot be stripped
automatically.

Just delete unhelpful ones, and move the rest onto separate lines
where they can be stripped.

Also remove a duplicated initialization of ROOTDISK.

In total, reduces script size on floppy by 1117 bytes, making room
for coming improvements.
